Application of Data Assimilation Methods to Reconstruct the 3–5 December 2015 Etna Eruption

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The assessment of volcanic hazards is crucial to develop effective emergency plans, especially for volcanoes close to urban areas or under air traffic routes. Impact assessment for expected scenarios relies on underlying numerical models that require eruption source parameters as inputs, and forecasts drastically depend on their robust ...

PalVol v1: a proxy-based semi-stochastic ensemble reconstruction of volcanic stratospheric sulfur injection for the last glacial cycle (140 000–50 BP) [PDF]

Earth System Science Data
Perturbations in stratospheric aerosol due to explosive volcanic eruptions are a primary contributor to natural climate variability. Observations of stratospheric aerosol are available for the past decades, and information from ice cores has been used to

Patterns of Plio‐Pleistocene Ice Volume Variability Recorded by the Large‐Magnitude Explosive Eruptions From the Kamchatka‐Kurile Volcanic Arc

Geochemistry, Geophysics, Geosystems
Marine fallout ash beds can provide continuous, time‐precise records of highly explosive arc volcanism that can be linked with the climate record. An evaluation of revised Plio‐Pleistocene (0–4 Myr) tephrostratigraphies from Ocean Drilling Program Sites ...

Climatic impact of volcanic eruptions [PDF]

Studies have attempted to 'isolate' the volcanic signal in noisy temperature data. This assumes that it is possible to isolate a distinct volcanic signal in a record that may have a combination of forcings (ENSO, solar variability, random fluctuations ...

Geomorphology and Age Constraints of Seamounts in the Cabo Verde Archipelago, and Their Relationship to Island Ages and Geodynamic Evolution

Geochemistry, Geophysics, Geosystems
The Cabo Verde Archipelago is related to a mantle plume located close to the rotational pole of the African Plate. It consists of islands and seamounts arranged in a horseshoe‐shaped pattern open to the west, thus forming two volcanic chains, each with a

Volcanogenic Dark Matter and Mass Extinctions

, 1996
The passage of the Earth through dense clumps of dark matter, the presence of which are predicted by certain cosmologies, would produce large quantities of heat in the interior of this planet through the capture and subsequent annihilation of dark matter

Andean volcanism, ocean fertilization, marine ecosystem turnover, and global cooling in the Late Miocene

Communications Earth & Environment
As the world’s longest active volcanic arc, the Andes deliver nutrient-rich volcanic ash directly to the ocean via atmospheric transport. This ash supplies key limiting nutrients to the Humboldt Current and the Southern Ocean, both critical for ...

Assessment of the atmospheric impact of volcanic eruptions [PDF]

The dominant global impact of volcanic activity is likely to be related to the effects of volcanic gases on the Earth's atmosphere. Volcanic gas emissions from individual volcanic arc eruptions are likely to cause increases in the stratospheric optical ...
